26-9-2023 REVILLA, ARAGON - COMMON WALL LIZARD (Podarcis muralis)

Podarcis muralis (common wall lizard) is a species of lizard with a large distribution in Europe and well-established introduced populations in North America, where it is also called the European wall lizard. It can grow to about 20 cm (7.9 in) in total length. The animal has shown variation in the places it has been introduced to. Fossils have been found in a cave in Greece dating to the early part of the Holocene.

The common wall lizard is a small, thin lizard whose small scales are highly variable in colour and pattern. Its coloration is generally brownish or greyish, and may occasionally be tinged with green. In some individuals, the row of spots along their backs may form a line, while others may have a reticulated pattern with dark spots on the side and scattered white spots that can be blue in the shoulder region. The tail is brown, grey or rust in colour, and may also have light bars on the sides. The belly region has six rows of larger rectangular scales that are generally reddish, pink, or orangish. Common wall lizards may also have dark markings on the throat. This lizard has six distinct morphological forms which are identified by the colouration of its throat and underbelly. Three of these are pure morphs consisting only of solid colours on their scales: white, red (orange) or yellow, and three other morphs are distinguished by a combination of colours: white-yellow, white-red and yellow-red.

The range of Common wall lizards includes much of mainland Europe except the north and very south and extends to Turkey. They inhabit rocky environments, scrubland, woodlands, orchards, fields, and urban areas. In the southern part of their range, these lizards tend to occur in humid or semi-humid habitats and prefer drier habitats in the north.

Common wall lizards are solitary diurnal reptiles that spend their days foraging, basking in the sun, or scurrying between rocks, rubble, debris, and buildings. They are adept climbers and diggers; if Common wall lizards can't find a natural shelter they will readily create their own burrow. These small creatures don't tolerate cold temperatures and during winter they hibernate underground until spring. Common wall lizards rely both on visual and chemical signals to communicate with each other. Males are equipped with femoral glands, which produce a waxy secretion used for chemical signaling; the compounds in their secretions are known to carry socially relevant information.
